Replace :: with : and it will "work", however there are some other
problems with the code you wrote. You modify the $commands array
without making it local, you also forget to local a few other things.
The following seems to work fine (i also put it in an autoloaded
_gradle file in $fpath):


#compdef gradle

local ret=1 state state_descr line
local curcontext="$curcontext"
local -A opt_args
local -a commands

_arguments -C \
   '--info[Log at the info level]' \
   '--stacktrace[Display stacktrace on error]' \
   '*:command:->command' \
   && ret=0

if [[ $state == command ]]; then
   commands=( "clean:Clean the project" "build:Build the project" )
   _describe -t commands 'gradle commands' commands && ret=0
fi

return ret
